Destructive Dimension

Set aside this game. Take your deck, then play another game. Both players start at 10 life.
In the smaller game, each player gets a token enchantment Destruction with "You have Hexproof. At your upkeep, sacrafice a creature, if you can't, put a time counter on Destruction. If Destruction has 3 or more time counters on it, you lose the game."
The winner of the other game gets to have control of all permanents played during the other game.
